Abstract
The present invention relates to a radiofrequency device (1) comprising: at least one sheet (2) of a substrate, and at least one wire booster aerial (3), formed with an electrically insulated conductor wire, comprising at least one turn, and having two ends connected to each other electrically in a connection zone (10).
Description
- The present invention relates to radiofrequency devices (RE devices) and more particularly those comprising an electronic component provided with an integrated antenna, electromagnetically coupled to an amplification antenna, called a “booster” antenna.
-
Patent application EP 1 031 939 discloses a RF device comprising an electronic component and several antennas. - Such RF devices are widely known.
- The presence of the booster antenna makes it possible to increase the range of radio interchange.
- To the applicant's knowledge, booster antennas are produced only by etching or screen printing.
- In order to electrically close the antenna, these techniques require the connecting of the ends of the latter via a strap (conductive bridge) which must pass through the turns of the antenna and therefore be insulated from the latter.
- In the case of screen printing, the insulation is obtained by means of a layer of an insulator which is deposited on the turns before the strap is formed, during a second screen printing pass.
- In the case of the etched antenna, the strap may be mechanically fitted. It then usually consists of an insulating layer made of plastic on which a conductive layer is deposited, the electrical conduction being provided by placing in mechanical contact, particularly swaging, or by the use of a conductive adhesive.
- The manufacture of these antennas is therefore relatively complex; it requires several operations on the same machine, and even several machines.
- In addition, their reliability is insufficient in the event of prolonged use when they are attached to a substrate that may undergo considerable deformations, because the ohmic resistance of the conductive tracks tends to increase in the mechanically stressed regions, which then adversely affects the performance of the antenna.
- It is also known practice to produce wire antennas by depositing an electrically insulated wire on a sheet of a substrate and to connect the ends of this wire to an electronic component such as a module. The connection to the module is achieved by thermocompression, with creation of an electric arc which causes a local melting of material and a local destruction of the insulation of the wire, or by soldering with solder.
- There is a need to further enhance the RB devices comprising a booster antenna.
- The subject of the invention is therefore a RF device comprising:
-
- at least one sheet of a substrate,
- at least one wire booster antenna formed with an electrically insulated conductor wire, comprising at least one turn, and having two ends electrically connected together.
- These two ends may be connected while being assembled directly to one another or may be connected by means of a fitted element, which is for example a conductor element having a low electric resistivity, advantageously at least partially metallic.
- Thanks to the invention, the manufacture of the antenna may be simplified because it is no longer necessary, since the wire is insulated, to produce the successive deposit of a layer of an insulator and a strap in order to electrically close the antenna.
- In addition, the use of a wire and not of a conductive track formed by screen printing or etching increases the reliability in the event of considerable mechanical stress of the substrate.
- The ends of the antenna may be connected together in a connection zone which is advantageously at a distance from the substrate, thanks for example to the presence in the sheet of substrate of a recess in which the connection zone is situated.
- By “at a distance from the substrate”, it must be understood that the connected ends of the antenna in the connection zone are not in contact with the substrate. They may come into contact with a filler material fitted to the substrate.
- Therefore, the sheet of substrate is not damaged during soldering of the antenna ends.
- The aforementioned conductive element may be placed in the recess, the ends of the wire being connected to this conductive element.
- The recess may or may not pass through the sheet of substrate.
- In one exemplary embodiment of the invention, the recess is filled with a filler material, which comprises for example a resin. This may make it possible to enhance the external appearance of the sheet of substrate once the ends of the antenna wire are connected together.
- The connection zone may be situated on the periphery of the antenna, which may enhance the quality of electromagnetic coupling with the electronic component, or elsewhere.
- The ends of the antenna wire that are connected together may be oriented substantially parallel or, as a variant, be oriented substantially perpendicularly.
- The ends of the antenna wire may be connected without the addition of material, or with addition of material, particularly addition of a metal alloy.
- The connected ends may be flattened, which makes it possible to limit the extra thickness that is if necessary generated in the connection zone.
- The antenna wire may be an enameled wire, particularly a copper-enameled wire. This wire may have a circular section, the diameter of the wire being for example less than or equal to 100 μm, better to 80 μm.
- The device may comprise at least one covering layer covering the antenna, on the side opposite to the sheet of substrate. This covering wire may be coated, on its face turned toward the antenna, with an adhesive.
- The antenna wire may be at least partially buried in the sheet of the substrate and/or in the covering layer. This burying may result for example from the technique used for placing the antenna wire on the sheet of substrate.
- The burying may result from the exposure of the wire and the sheet of substrate to ultrasound vibrations.
- At least one of the sheet of substrate and the covering layer may comprise fibers, which may comprise paper fibers, for example cellulose fibers.
- The RF device may have no electronic component. As a variant, the RF device may comprise an electronic component provided with an integrated antenna, electromagnetically coupled via a contactless link to the booster wire antenna.
- The electronic component may comprise a chip attached to a substrate on which the integrated antenna is produced, such a component also being called an antenna module. The electronic component may also be a chip already having its antenna on the silicon, a flexible or rigid inlay, a prelam or a card with a plastic base in particular.
- The sheet of substrate may comprise at least one recess in which the electronic component is at least partially engaged. This may make it possible to reduce the thickness of the RF device.
- The electronic component may have a stepped shape with a widened base portion. The sheet of substrate may comprise a recess receiving this base portion, the thickness of the sheet of substrate being able to correspond substantially to that of the base portion.
- The electronic component may be situated inside or outside the turns of the booster antenna, when the latter is observed from above. The turns of the antenna may extend substantially in one plane.
- The electronic component and the booster antenna may belong to the same sheet of substrate or be made on different sheets.
- A further subject of the invention is an assembly comprising:
-
- a RF device as defined above, with no electronic component electromagnetically coupled to the booster antenna, and
- at least one electronic component that is able to be separated from the RF device and that comprises an integrated antenna that is able to be electromagnetically coupled to the booster antenna.
- The RF device may be integrated into a first article and the electronic component may be integrated into a second article able to be attached to the first so as to achieve the electromagnetic coupling between the integrated antenna of the electronic component and the booster antenna of the REF device. The second article may be able to be separated from the first, if necessary.
- The first and second articles may be security documents. The first article may for example be a passport and the second article a visa designed to be bonded or stapled to this passport.
- The first article may also be a card for identification, payment or subscription and the second article a temporary coupon for validation of the card.
- The first article may also be a card-holder and the second article a card arranged in order to be housed in the card-holder.
- A further subject of the invention is a method for manufacturing a RF device, comprising the following steps:
-
- placing on at least one sheet of a substrate an electrically insulated wire so as to form at least one turn of a wire antenna,
- electrically connecting two ends of the antenna together by local melting of material, the ends being, during this connection, sufficiently distant and/or thermally insulated from the substrate in order to prevent damaging the latter.
- The connection of the ends may take place in or above a recess of the sheet of substrate, which makes it possible to prevent a contact of the substrate with the high temperature material during the connection.
- An electric conductive element may be placed in the recess of the substrate and the connection of the ends may be achieved by means of this conductive element or on the latter.
- For example, the two ends of the antenna wire may be soldered to the conductive element, which electrically closes the antenna, or as a variant be soldered together and to the conductive element, the latter then playing no electrical role.
- The connection of the ends of the antenna wire may also be carried out against an anvil of a support on which the sheet of the substrate may be placed, through the recess. This anvil is for example a wearing part fitted to the support, and may protrude on the support, so as to be engaged at least partially in the recess.
- The connection may also be achieved after inserting an anvil between the ends to be connected and the sheet of substrate. The aforementioned recess may in this case notably be deleted.
- The ends to be connected may be oriented in parallel and held clamped laterally against one another during the connection, or be substantially perpendicular before the connection.
- The antenna wire may be placed on the substrate with at least partial varying in the latter, by local melting of the sheet of substrate.
- The thickness of the antenna wire may be partially or completely compensated for by the adhesive(s) and assembly materials.
- A recess may make possible the partial or total compensation for the thickness of the electronic component when the latter is present, in order to prevent it from protruding.
- The invention may be better understood on reading the detailed description that follows of nonlimiting exemplary embodiments of the latter, and on examining the appended drawing in which:
-

FIG. 18 is a view similar toFIG. 1 of another exemplary embodiment of the invention, and -
FIGS. 19 and 20 are views similar toFIG. 2 of other exemplary embodiments of the invention. - In the figures, the relative proportions of the various elements represented have not always been observed, for the purpose of clarity of the drawing.
-
FIGS. 1 to 3 represent aninlay 1 comprising asheet 2 of a substrate, anantenna 3 and acovering layer 4 coated on its surface turned toward thesheet 2 with alayer 5 of an adhesive. - The
antenna 3 is a wire antenna, being formed by the winding on thesheet 2 of an enameled copper wire, in order to form several concentric turns. - In a
region 8, thewire 3 of the antenna passes through the turns in order to allow the two ends of the wire to join in aconnection zone 10 situated on the periphery of the antenna. - In the example in question, the ends of the wire are connected together on a
conductive element 12, which is for example metallic and received in arecess 13 of thesheet 3, as can be seen inFIG. 3 . - The ends of the wire of the antenna are for example assembled together by thermocompression, thanks to a thermocompression device which makes it possible to raise the wire to a temperature sufficient to cause it to melt.
- The wire used is for example an enameled copper wire and the soldering by thermocompression makes it possible to locally destroy the enamel.
- The RF device also comprises an
electronic component 20, for example an RFID device, which includes an integrated antenna, electromagnetically coupled to thebooster antenna 3. - The
electronic component 20 may be situated inside the turns, as illustrated inFIG. 1 , in a location that is for example determined so as to optimize the electromagnetic coupling with thebooster antenna 3. - As a variant, as illustrated in
FIG. 18 , theelectronic component 20 may be situated outside the turns. - The
electronic component 20 may be an antenna module or an inlay, capable where necessary of operating in a standalone manner, comprising a substrate on which the integrated antenna is produced, for example by etching or screen printing, and which is connected to the chip, the latter being for example of the flip chip type, arranged so as to allow a connection with the substrate by contact when it is deposited. - The
electronic component 20 may comprise at least one memory and a processor making it possible to read and/or write in the memory, the antenna module may comprise a microprocessor notably. - If necessary, the
electronic component 20 may comprise at least one sensor of at least one environmental condition, for example a sensor of humidity, temperature, relative humidity, light, or be sensitive to an outside stimulus, for example the presence of a compound or an organism. - The
electronic component 20 may also, if necessary, comprise at least one liquid crystal or light emitting visual indicator, and/or a fingerprint sensor. - The
electronic component 20 may comprise, as illustrated, a widenedbase portion 26 whose thickness corresponds substantially to that of the sheet of the substrate, that is received in recess 22 of thesheet 2, theupper portion 24 of thecomponent 20 being received in arecess 25 of thecovering layer 4 and of theadhesive layer 5. - The total thickness of the
sheet 2, thecovering layer 4 and theadhesive layer 5 may correspond substantially to the total height of theelectronic component 20, such that theinlay 1 has a substantially uniform thickness over the whole of its extent. - Preferably, the
connection zone 10 is situated on the outer periphery of the antenna, but in a variant not illustrated, thisconnection zone 10 may be inside the turns. The presence of theconnection zone 10 on the periphery of theantenna 10 may enhance the homogeneity of the electromagnetic coupling with the integrated antenna of theelectronic component 20. - The ends 30 and 31 of the wire of the
antenna 3 may be oriented substantially in parallel when they leave theconnection zone 10, as illustrated inFIG. 4 , or arrive in parallel from the same direction. - As a variant, as illustrated in
FIG. 5 , these ends 30 and 31 may be oriented substantially perpendicularly. - In the example represented in
FIG. 19 , theelectronic component 20 is received in a layer 7 forming part of theinlay 1. - The
inlay 1 may be produced without theelectronic component 20, the latter then being outside theinlay 1, as illustrated inFIG. 6 . - In a variant represented in
FIG. 20 , the electronic component is received in a layer 9 that does not form part of theinlay 1. - Whether or not the
electronic component 20 is present, the inlay may comprise thesheet 2 and thecovering layer 4 without theintermediate layer 5 of adhesive, as illustrated inFIG. 7 . Theantenna wire 3 may, in this case, notably be at least partially buried in thesheet 2 and/or in thecovering layer 4 so as not to generate excessive extra thickness above theantenna 3. - The assembly of the
ends - When a fitted
element 12 is present in arecess 13 of thesheet 2, as illustrated inFIG. 8 , the thermocompression may be carried out against this fittedelement 12, which is designed to withstand the heat generated during assembly. The fittedelement 12 is for example a metal element, for example a copper plate. - The ends 30 and 31 may be assembled each to the
conductive element 12 without being assembled directly together. As a variant, the ends 30 and 31 may be assembled together without being assembled to the fittedelement 12, the latter serving as an anvil during the thermocompression and possibly not being electrically conductive. As a further variant, the ends 30 and 31 may be assembled together and to the fittedelement 12. - The
sheet 2 may also have no fittedelement 12 and the assembly of theends recess 13 against ananvil 40 which protrudes on asupport 45 on which thesheet 2 rests. - The
support 45 may comprise, as necessary,several anvils 40, as illustrated inFIG. 10 , particularly when several inlays are produced from one and thesame sheet 2. - Each
anvil 40 is for example designed to be able to be attached removably to thesupport 45, in order to serve as a wearing part. - Each
anvil 40 is for example made of a temperature-resistant ceramic. - Once the
ends FIG. 13 , afiller material 50 may be inserted into therecess 13, as illustrated inFIG. 14 , in order to prevent the presence of a hole on theface 52 of the inlay opposite to thecovering layer 4. - The assembly of the
ends sheet 2 and theends anvil 53 whosefoot 54 engages under theends thermocompression tool 60 may comprise, as necessary, one or more inclined faces 61 making it possible to laterally compress the two ends 30 and 31 against one another. - If necessary, as illustrated in
FIG. 12 , thethermocompression tool 60 may press on theends jaws - The invention applies to the production of an inlay that may or may not comprise, as has just been described, an
electronic component 20 including an integrated antenna electromagnetically coupled to the booster antenna. - When the inlay comprises the
electronic component 20, the latter may for example be integrated into an article, for example a security document, by replacing the conventional inlays comprising a wire antenna whose ends are electrically connected to an electronic chip or to a module. - The invention may also be applied by placing the
booster antenna 3 on a first article and theelectronic component 20 on a second article. - The first article is for example a card-
holder 70 as illustrated inFIG. 15 , theelectronic component 20 being supported by acard 71 designed to be inserted into the card-holder 70. Therefore, the card-holder 70 may provide additional security against unauthorized use of thecard 71, making it more difficult to use the latter in the absence of the card-holder 70. - The first article comprising the
booster antenna 3 may also be apassport 73, thebooster antenna 3 being for example integrated in the cover of the passport. The second article may be avisa 74 comprising theelectronic component 20. Thebooster antenna 3 of the passport makes it possible to read information contained in theelectronic component 20 of the visa. - The first article may also be, as illustrated in
FIG. 17 , acard 76 for identification, payment or subscription, comprising for example a photograph of the user and received in one of the flaps of acase 78 comprising two flaps. The second flap may receive atemporary coupon 80 incorporating theelectronic component 20 whose integrated antenna is electromagnetically coupled to thebooster antenna 3 of thecard 76 when thecase 78 is closed. - Naturally, the invention is not limited to the exemplary embodiments that have just been described.
- In particular, the
sheet 2 of substrate may be of any type, comprising for example a film made of plastic and plies of paper. - If necessary, the
sheet 2 of substrate may have a composite structure and comprise at the same time at least a plastic and paper fibers. - The
sheet 2 of substrate may comprise cellulose fibers. - The
covering layer 4 may have other structures, comprising for example a plastic film and/or one or more plies of paper. - The expression “comprising one” must be understood as being synonymous with “comprising at least one”, unless it is specified to the contrary.
